The value of the account at the child's twenty-first birthday will be $24183.83.
Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
At the time of her grandson's birth, a grandmother deposits $13,000 in an account that pays 3% compounded monthly.
Assuming that no other deposits or withdrawals are made during this period.
Then the value of the account at the child's twenty-first birthday will be
A = 13000(1 + 0.03)²¹
A = $ 24183.83
